Spatial and seasonal patterns of taxonomic, functional, and phylogenetic diversity of fish assemblages in island waters of Zhejiang, China: associations with environmental, climatic, and socioeconomic factors
Fish assemblages play a crucial role in maintaining island ecosystem health, yet comprehensive diversity analyses in China’s island waters remain limited. A recent study evaluated taxonomic, functional, and phylogenetic diversity across eight Zhejiang islands, revealing significant variation—with northern islands exhibiting the highest values. Structural equation modeling highlighted a positive relationship between marine environmental factors and diversity (0.675), a negative socioeconomic impact (-0.173), and an indirect, negative climate influence (-0.456).
Compositional convergence of island demersal fish assemblages in the East Sea: a long-term trammel-net comparison between Dokdo and Ulleungdo
Rapid ocean warming is fundamentally reorganizing marine fish assemblages, yet definitive, long-term evidence of compositional convergence between adjacent island ecosystems remains limited. A recent study published by World Data Ocean analyzed two decades of standardized trammel-net surveys around Dokdo and Ulleungdo in the East Sea, revealing a significant decline in inter-island dissimilarity between 2013 and 2025.
